hi

OpenStudy (anonymous):

;)

OpenStudy (anonymous):

Do you need help in math?

OpenStudy (anonymous):

yeah... I am trying to write out the problem

OpenStudy (anonymous):

Oh okay

OpenStudy (michele_laino):

Hi! what is your Mathematical problem?

OpenStudy (anonymous):

f(1[x]1)=\neg;[3]x(1[x-7]1)(1[[[x]^[2]]-25]1)

OpenStudy (anonymous):

\[f(x)= -3x(x-7)(x^2-25)\]

OpenStudy (anonymous):

@Nnesha can you help me

OpenStudy (anonymous):

is this.... 0, 7, 5

OpenStudy (michele_laino):

@mathgirl2012 are you ask for zeroes?

OpenStudy (anonymous):

yeah... Sorry I forgot to put that UGH...

OpenStudy (anonymous):

@Nnesha

Nnesha (nnesha):

what is your question ??

OpenStudy (anonymous):

to find the zeros of f(x)=−3x(x−7)(x2−25) I think the anwsers are 0,5,7

OpenStudy (anonymous):

f(x)=-3x(x-7)(x^2-25)

OpenStudy (anonymous):

Is hte equation

Nnesha (nnesha):

|dw:1416171460515:dw|

Nnesha (nnesha):

distribute by -3x

OpenStudy (anonymous):

Did I get it right... I put up 0,7,5

OpenStudy (anonymous):

??

OpenStudy (michele_laino):

I think are: 0, 7, +5 and -5

Nnesha (nnesha):

what is the highest degree after distribution

OpenStudy (anonymous):

oh yeah cause \[\sqrt{5} is \pm5\]

Nnesha (nnesha):

|dw:1416172740527:dw| your highest degree is 4 so must have 4 zeros
